At this time, I think your posture must be nonstandard, so you must pay attention to posture training when exercising. Many people who keep fit say that they would rather do less and do more standard movements. I think this sentence is the truth, because only by knowing the standard of doing can we exercise better. Many times, if your movements are not standard, then in fact, your effect last year will not be achieved, and you will feel that although you have practiced for a long time, it is useless.
So I think you should train your muscles and do your work in a more standard way at this time, because this will improve your overall coordination, and then you won't feel particularly tired when you do some exercise. Then you can see the effect that your muscles grow faster, which is definitely helpful for your later fitness, so you must make the movements standard.
